Draining Sound from rear pass. side

Gang -
I have been out driving my car lately and have a question about something that has either just popped up or has been there I finally noticed it.

When I get home I shut down the car (obviously). Then for about 5 seconds I hear what sounds like water draining down a pipe on the rear passenger side of the car? It almost sounds like it's in the rocker panel. It doesn't sound like it's coming from the dash but I could be wrong.

Could it be fuel going through some lines? I'm at about 3/4 tank.

It's not a gurgling sound but does sound like water going through a pipe.

I have done some searches and see things like "air in the coolant line" to blown head gasket.

Temps are good and coolant looks normal. It is a tad low. (about .5" - .75" below full when cool line. I'll fill it on Monday with Dexcool.

Please let me know what you think it is.

Car is a 99 with about 40500 miles on it.

God I hope it's not a head gasket!!!!

I don't think so but I am no mechanic

I was running it today when it happened but I was not running the AC yesterday when I first noticed it.

I ran the heater today (1 cycle) to see if that made a difference. I sure sounds like water /coolant is flowing around in there someplace.

Maybe it's brakefluid? I do let off the brake right after a kill the engine. I'll have to test that next time I go out for a ride. I'll hold the brake down and pay attention to when I release it.

I like your theater, I ran a high end A/V shop here in austin for the last 12 years You did a nice job. :thumbsup:

good news is if you dont smell any antifreeze in the exhaust and no smoke

it's probably not a head gasket, you might look under your oil cap to see if there is any foaming but i think it must be something else .

Good luck I'm sure you'll track it down

Thanks for the comments on the HT.

I looked under the oil cap and so nothing out of the ordinary. No foam no white dust or bubbles.

Things are making sense now!!! This morning I took the boy to school. When I stopped I heard nothing. Then I drove to work. When I stopped the car I heard nothing. One common factor between both of these stops... I was on flat ground.

The one common factor between the two times I heard the noise.... I parked on my driveway first to open the garage door. It is one a steep incline. Then I drove into the garage and parked the vette. Then I hear the gurgling noise. Interesting.....
I bet it's fuel.
